CREAM SEBARATOR- FR MLK CONTAINERS.

Application filed June 26. 1922.

l/'o all w/mm t may concern:

Be it known that we, lecon E. Maren, tiresome linnn, and Cniirn'yon E. Rini-ann, all citizens ot' the United States, and resi- 3 dents oit Milwaukee, inthe county oi Milwaukee and State oi llflisconsin, have invented certain new and usetul Improvements in Cream Separators tor Milk Containers; and we do hereby declare that the following` is i0 a full, clear, and exact description thereof.

ur invention refers to cream separators and it has for its object to provide a simple siphon tube ttor separating the cream Yfrom original containers or. bottles. rllhe con- ].5 struction and arrangement ot' the siphon is such that it can be inverted and immersed in the neek of the bottle tor receiving an initial volume or cream that will extend beyond the return bend, whereby the Siphon is started when inverted 'for delivery purposes, the long leg of the Siphon being intermediately bowed both for the purpose of preventing the Siphon, when inverted, from dropping too tar in the bottle, and to hold the discharged end ot the Siphon in its proper delivery position when in operation.

With the above objects in view, the invention consists in certain peculiarities ot construction and combination of parts as set forth hereinafter with reference to the accompanying illustrations and subsequently claimed.

In the drawings,

Figure l represents a sectional elevation of a portion ot a milk bottle, having tted therein, an inverted Siphon embodying the -teatures of our invention, the siphon being in position to receive a predetermined filling ot cream, whereby it will automatically draw oit the cream when it is removed and inverted to a delivery position, and

Figure 2 is a Similar view showing the Siphon in its delivery position.

Referring by characters to the drawing, A represents the mouth or lip of a standard milk bottle B. Referring to Figure 2 of the drawings, the Siphon is shown in its cream delivery position, with relation to the bottle contents, and the short leg ot the siphon is of a length approximately equal to the depth of the cream contained in the bottle. The short'leg ot the Siphon is merged into a return bend or throat 2, which throat rests upon the lip of the bottle and the longv or discharge leg 8 of the Siphon, is

bowed inwardly or towards the straight leg intermediate ot' its lenth, as indicated. at X. The bowed intermediate portion ot the longl leg' engages the side walls ot the hottle and terms a rest 'tor the Siphon, whereby it will assume its proper position with relation to the bottle and the discharge end 3 of the long leg; ot said Siphon is thus positioned obliquely orflared outwardly 'from the side wall. of' the bottle, whereby a clearance between the bottle and the discharge mouth oit said leg is otl suiicient distance to permit clearance between the associated wall ot the bottle tor placing a cream receiving; container under the mouth 3 ot said len:

ln the operation ot the device, tor sanitary reasons, the siphon is started by simply inverting it and dropping` the inverted short legand the upper portion ot' the bowed long` leg into the mouth of the bottle, the intermediate bowed portion X beingso proportioned with relation to the ent `ance of the short len` that the Siphon will, in a standard mouth bottle, drop the required distance into the neck to receive a column of cream which is ot sufficient volume to start the Siphon in a discharging action when it is reversed, as shown in Figure 2 of the drawings. After the initial column has entered a portion oit the short leg' and portion of the long` leg ot the siphon, the operator may close the discharge end or mouth ot the Siphon leg 3 by the thumb or any suitable closure, whereby the column ot cream, partly filling' the siphon, will remain intact momentarily, while said siphon is being' inverted to assume a position shown in Figure l with relation to the bottle. Thus the Siphon is started automatically and it will discharge approximately the entire body ot cream from the upper portion ot the milk, which bottle ot cream would automatically rise .and assume a depth in the neck of the bottle, as indicated in the drawmg'.

The siphon is preferably formed from glass, for sanitary reasons, but it may be formed `from other materials, it desired, such an aluminum or metal. The Siphon may be made flexible to facilitate its proper shaping and its insertion into the bottle. Owing to the fact that there are no obstructions or detachable parts associa-ted with the siphon, it can be readily sterilizechand of course the 'manufacture is consequently reduced to n minimum, whereby it can be sold to the trade -tor a, comparatively small sum.

Brieiiy, the invention meets the requirements of a device of this character for all household purposes.

`We claim:

A. Siphon for removing cream from milk bottles comprising ashort erin und e ionp; arm; said arms being joined by a continuons semi. circular bend; Seid bend being adapted to rest upon the lip of the bottle with said short arm downwardly and inwardly directed; said long arm having n second bend therein adapted to rest on the neck of the bottle, the end of said long erm being Meneer outwardly directed from said Second bend tor 'feeding liquid outwardly into zi container; said first mentioned bend being of such dimension and said arms being so ndjacent as to permit the insertion of said tirst mentioned bend into the bottle for charging the Siphon.

In testiinonjt7 that We claim the foregoing We have hereunto set our hands at Milwaukee in the county of Milwaukee and State of `Wisconsin JACOB E. MAIER. NCHOLAS LENZ. CLARENCE E. RADMER
